Washington (CNN) - President Barack Obama spared few from his zingers at Saturday's White House Correspondents' Dinner - including himself.

He stepped to the podium as DJ Khaled's "All I Do Is Win" played as an introduction and told the audience, "Rush Limbaugh warned you about this - second term, baby."

His advisers were "a little worried about the new rap entrance music," and suggested that he kick off his speech with jokes at his own expense to "take himself down a peg." But, the president responded, "after 4½ years, how many pegs are there left?"

Tune to CNN from 9-11pm ET for live coverage of the White House Correspondents' Dinner.

(CNN) - Texas Gov. Rick Perry is demanding an apology from a California newspaper that published a cartoon that seemed to link his push for less regulations to the recent fertilizer plant explosion that killed 14.

"The Sacramento Bee published a disgusting 'cartoon' mocking the deadly explosion in West. While I will always welcome healthy policy debate, I won't stand for someone mocking the tragic deaths of my fellow Texans and our fellow Americans. I have written the editor and asked that they apologize to the citizens of West," Perry wrote on his official Facebook page.

McCaul, R-Texas, said the complaint could have been filed later and suggested a change in the Miranda laws allowing American citizens accused of terrorist activities to be questioned for at least 48 hours.FULL POST

(CNN) - Forced government-wide spending cuts reduced staffing of air traffic controllers and slowed the aviation system this week, resulting in flight delays for travelers. But congressional intervention permitting new budget flexibility that allows them to return to work has, for the moment, reignited fierce political debate over spending and taxes.

President Barack Obama and some Capitol Hill Democrats complained that Washington was now unwisely picking winners and losers after congressional inaction on deficit reduction earlier this year triggered $85 billion in government-wide spending cuts.FULL POST
